I recently installed some BikeVis LED lights. From looking through other aux light posts, I found that Darren (Gas_Up_Lets_go) made wiring kits with a switch, he also made the mounting brackets for me. Extremely helpful and installation was very quick and easy with the instructions provided. PM him for more detail.
Here are the ones that I fitted to my Ten.
